Polite professional responses – from the experts.

I thought these responses to the BEST study from the leading experts are worth posting (comments collected by our friends at the UK Science Media Centre). A far cry from the response of ideologues such as Anthony Watts and Andrew Bolt:

“Clearly this study needs peer review, but if correct it is pleasing to hear that this new analysis conforms with US work at NASA and NOAA and that of Phil Jones and his colleagues at the UK Hadley Center-UEA Climatic Research Unit. This work adds to the evidence about how climate change is

Others have also commented:

Prof Peter Cox, Professor of Climate System Dynamics, University of Exeter, said:

“These studies seem to confirm the global warming estimated from the existing datasets, which is pleasing but not exactly a surprize to those of us who know how carefully the existing datasets are put together. It is surprizing however that the authors believe that this news is so significant that they can’t wait for peer-review, especially when their conclusions aren’t exactly revolutionary.”

“While I have not seen the paper, and recognise the results have not been peer reviewed, I am very encouraged that their preliminary analysis supports previous analyses of the UK Hadley Center-UEA Climatic Research Unit, and the US analyses of NASA Goddard Institute of Space Sciences, and NOAA. All previous analyses paid particular attention to removing the urban heat Island effect – this new work appears to show that they did this successfully”

Prof Phil Jones, Director of the Climatic Research Unit, UEA, said:

“I look forward to reading the finalised paper once it has been reviewed and published. These initial findings are very encouraging and echo our own results and our conclusion that the impact of urban heat islands on the overall global temperature is minimal.

Prof Chris Rapley, Professor of Climate Science at UCL, said:

“I think it would be very unwise to comment until the peer review process has completed. If we have learned anything over the last couple of years it is surely that ensuring the rigour of the science is paramount – however good the “scoop” might seem.”

“If and when such a study is peer-reviewed and published, hopefully we can then focus on the implications for the future of this warming rather than wrangling over whether the warming is really there.”

Prof Simon Tett, Head of Global Change Research Institute School of Geosciences, University of Edinburgh, said:

“Earlier analysis, including that from the Climatic Research Unit, using a restricted set of temperature records, to avoid urban warming, show large scale warming. Comparison of that data with climate models leads to the conclusion that anthropogenic drivers are responsible for the late 20th century warming. The BEST study, assuming its results are similar after peer review, would not change that view.”

“This new study confirms what we already knew. The warming of the land areas of the Earth since the 19th century cannot be explained by the impact of cities growing to engulf rural weather stations. So-called ’sceptics’ should now drop their thoroughly discredited claims that the increase in global average temperature could be attributed to the impact of growing cities, which create an urban heat island effect. This claim was always dubious as oceans also show the same level of warming as land areas. The warming of the Earth is unequivocal and, as every major scientific organisation in the world has pointed out, the overwhelming evidence indicates that this warming is being driven by the unarguable increase in greenhouse gas concentrations in the atmosphere. More broadly this study also proves once again how false it was for ’sceptics’ to allege that the e-mails hacked from the University of East Anglia proved that the Climatic Research Unit’s land temperature record had been doctored. Several independent inquiries, and now this study, have shown that allegation to be entirely untrue. It is now time for an apology from all those, including US Presidential hopeful Rick Perry, who have made false claims that the evidence for global warming has been faked by climate scientists.”
